Su Jie's mouth curled into a smile. At this farm that churns out two million pigs a year, an average of over five thousand pigs were slaughtered every day, the Soul Summoning Banner alone could condense nearly twenty Yin Souls in a single day.
Including the output from other farms, as well as the slaughter of cattle, sheep, and meat chickens, that added up to thirty to forty Yin Souls a day, easily exceeding ten thousand Yin Souls over the course of a year.
No need to kill a single person, one could effortlessly obtain a large number of Yin Souls.
This was something the cultivators of Tianyuan World would find difficult to accomplish, given their low productivity. To slaughter five thousand pigs, they would have to scour several cities and surrounding towns, going door to door to redeem them.
With that effort, it would be more efficient to just kill people.
But in modern society, a large farm could easily achieve this, and that was just the slaughter volume for one day.
